Cap-rotating type fidelity bottle cap described in the utility model is made up of three parts: bottleneck structure, upper and lower cover structure, core plug structure.
Bottleneck structure is to be made of a bottleneck cylinder (18), bottleneck cylindrical center upper end is a round bottle oral pore (17), around in the bottleneck hole be one greater than cylindrical round platform, round platform has constituted bottleneck end face (16) and bottleneck retaining ditch (15), below the retaining ditch, the outside of bottleneck cylinder four retaining strips (20) that distributing equably, bottleneck cylinder lower end is enclosed within on the bottle.
The core plug structure is to be made of one group of patch (2) that a core plug (1) core is overlapping beyond the Great Wall, core plug top is a core plug edge (4) greater than the core plug, handle (7) is connected along top (5) with the core plug, for anti-skidding, establish a handle aperture (6) on the handle, the core plug is inserted in the bottleneck hole together with patch, and the two is a transition fit, very ends with the contact of bottleneck end face to the core plug along following (3).
A lower cover apical pore (13) is arranged at lower cover (22) top, and there are four well-distributed retreat stop blocks (14) lower cover inwall upper end.The heating lower cover is enclosed within it on bottleneck cylinder to certain temperature, makes the lower cover apical pore be inserted in core plug handle, and is pressed on the bottle (19), fits along top (5) with the core plug to lower cover inner face (12) and ends.At this moment, lower cover inner face (12) is fitted along top (5) with the core plug and is ended.At this moment, the retreat stop block on the lower cover inwall (21) is because the effect of bottleneck cambered surface,, and tightly is against in the bottleneck retaining ditch for being inclined upwardly from downward-sloping upset.Retreat stop block and bottleneck retaining strip are in sustained height, the staggered installation.Because the mutual barrier effect of retreat stop block and retaining strip, the lower cover inwall can not rotate and can not withdraw from relative to bottle.Lower cover inwall and bottleneck cylinder bearing fit.So far lower cover, bottle, core plug have been finished mutual location, connect, and install.
Lower cover is by four retreat stop blocks and bottle location mutually, and retreat stop block is not only thin but also narrow to have formed a weak ring, and before it did not destroy, the core plug can't be extracted from the bottleneck hole, promptly can not uncork.
Loam cake (11) is enclosed within on the corresponding face of cylinder of lower cover by the knock hole on it (9) bearing fit and locatees, with the positioning table on it (10) stop.And with lock ring (8) with the two pinning, suitably exert oneself just to close or open, like this good airproof performance.Lock ring be by the semicircle scrobicular ring that covers down and on semicircle bulge loop two parts of covering constitute.
Another kind of scheme is not establish retaining strip on the bottleneck cylinder, and does a biconvex helical surface in the bottom of bottleneck cylinder, correspondingly does a concave-concave helical surface (24) in the lower cover bottom, and during assembling, two helical surfaces are fitted fully.This is a force-increasing mechanism, when making the circumference tangential force be transformed into vertical forces, but the reinforcement several times.
For anti-skidding, increase friction, outside lower cover, be carved with straight burr groove (23).
When needs were opened bottle cap, left hand was held bottle, and the right hand is pulled up loam cake, holds lower cover straight burr groove section then, and clockwise direction rotates lower cover, because of under the retreat stop block that covers and the retaining strip on the bottleneck stop mutually, and can not rotate.So slightly once weak ring firmly by disconnected along circumferential shearing and destroy, upwards take down lower cover, can extract the core plug, then bottle is opened.
For II type bottle stopper, because of the helical surface effect, the vertical direction that also will make progress when lower cover rotates in the clockwise direction moves and reinforcement.And retreat stop block is tight against on bottleneck retaining ditch, and it can not be moved, thus one exert oneself slightly, and under the force-increasing mechanism effect, weak ring is just vertically sheared disconnected and is destroyed.
